Pneumatic/Hydraulic Actuator

1. The gearbox uses a parallel dual-guide stabilization design, incorporating a transmission stabilization design concept for the first time. It is an upgraded product of a common fork actuator. Structural strength, transmission efficiency, and transmission stability are all improved.

2. Pneumatic priority and ESD function emergency priority under any circumstances: When pneumatic operation is in progress, regardless of the position of the manual pump selector switch, the control system can operate the pneumatic control valve according to the given control signal.

3. The patented multi-functional manual pump allows for all-round operation. The hydraulic control conversion isolation circuit allows for testing the functions of the control system under pressure and performing online maintenance of the valve and actuator without actuating the valve.

4. It uses a Hall-effect sensor button with an embedded design for impact and misoperation protection. It improves the control unit PLPG2010 operating performance, explosion-proof rating Exd ICT6, and protection rating IP68.

5. Breaking through traditional design: Completely eliminating oil spraying during the use of pneumatic-hydraulic isolation and pneumatic-hydraulic combined actuators.

6. The use of an integrated insulating filter solves both gas filtration and electrical insulation, and allows for online cleaning to ensure the accuracy of pressure transducer detection and the cleanliness of the actuator air source.

7. For valves driven under the same conditions, the CDG actuator reduces size and weight, resulting in a smaller form factor. This reduces the space occupied by the actuator mechanism and lightens the load on pipelines and valves.

8. The actuator control system is designed for low pressure (0.4 MPa), solving the problem that a considerable number of pipeline pneumatic-hydraulic combined actuators cannot operate normally. It can operate at high pressures up to 16 MPa.

9. Improves actuator response time and speed, reducing emergency shutdown accident duration, and solving the problem of large-diameter valves being unable to achieve fast shutdown.

10. Optimizes actuator space layout, solving the problem of operators needing to operate the actuator on both sides of the pipeline, and simultaneously improving escape space for operators in emergencies.

11. Uses a fully welded oil cylinder to reduce weight and eliminate oil leakage.
